Description
Technical Field
[0001] This utility model relates to the field of electrode cutting technology, and in particular to a dust extraction device for electrode cutting. Background Technology
[0002] As market demand for new energy vehicles gradually increases, battery pack safety has become a key concern for consumers. For power battery manufacturers, strictly controlling product quality during the cell production process is crucial to reducing the risks associated with battery pack use.
[0003] In the ultrasonic welding process of battery cells, tab cutting is an indispensable process. Because metal shavings are generated during cutting, if burrs or shavings enter the battery cell, they may puncture the separator and cause an internal short circuit, which seriously affects the safety and quality of the battery cell.
[0004] Existing dust removal devices for electrode cutting mechanisms generally employ an upward airflow method. This method uses upward airflow to carry away the debris generated during cutting, causing the metal debris to automatically fall into a debris box and be vacuumed as it passes through the conveyor channel. However, during the existing airflow dust removal process, the cut electrodes still splatter on the machine, and there is still some small burr debris flying around. The reliability of particulate matter control at the machine position is poor, which cannot guarantee the quality of battery cell manufacturing. Utility Model Content

[0011] A dust removal structure includes a sealed housing and an air intake pipe. The sealed housing is mounted on the frame, and the air intake pipe is connected to the sealed housing to form a negative pressure space within the sealed housing.
[0012] The sealing housing is connected to the dust collection channel, and the sealing housing is also provided with a dust collection container, which has a collection port that corresponds to the dust collection channel along the first direction.
[0013] Furthermore, the dust collection hood protrudes from the electrode positioning part along the first direction, and the dust suction port is opened on the side of the dust collection hood corresponding to the electrode positioning part.
[0014] Furthermore, the frame includes a base plate with through holes, the cutting mechanism and the dust collection hood are both disposed on one side of the base plate, and the dust collection hood is installed at the through holes;
[0015] The dust removal structure is spaced apart on the other side of the substrate, and the dust collection channel is connected to the through hole and connected to the sealing shell.
[0016] Furthermore, the sealing housing includes sidewalls arranged at relatively intervals, the sidewalls being parallel to the first direction, and an air intake port being provided on the sidewalls, with the air intake pipe connected to the air intake port.
[0017] Furthermore, the dust collection channel and the collection port are arranged at intervals along the first direction, the air intake is correspondingly located at the interval between the dust collection channel and the collection port, and a filter cover is also installed at the end of the air intake pipe corresponding to the air intake interface.
[0018] Furthermore, a sealing door is movably installed on the sealed housing, and the dust collection container is detachably installed in the sealed housing.
[0019] Furthermore, the cutting mechanism includes a first mounting plate, a second mounting plate, a guide member, and a driver. The first mounting plate is fixedly mounted on the frame, and the second mounting plate is arranged at a distance from the first mounting plate along the first direction.
[0020] The guide member is fixedly connected to the first mounting plate, the second mounting plate and the guide member are guided and cooperated along the first direction, the driver is driven and connected between the first mounting plate and the second mounting plate, and the cutting part is assembled on the second mounting plate.
[0021] Furthermore, the second mounting plate is also equipped with a linear bearing, the guide member is guided and engaged with the linear bearing, the driver includes a cylinder and a push rod, the cylinder is fixedly connected to the second mounting plate, and a floating joint is connected between the end of the push rod and the first mounting plate.
[0022] Furthermore, the frame also includes a base and a plurality of columns, the base and the substrate are arranged at intervals along a first direction, the plurality of columns are respectively fixedly connected between the base and the substrate, and the sealing housing is fixedly connected to the side of the base facing the substrate.

[0024] Compared with the prior art, the advantages of the electrode cutting and dust extraction device of this utility model are as follows: the electrode cutting and dust extraction device adopts the design of frame, cutting mechanism, dust collection hood, dust collection channel and dust removal structure. The cutting mechanism includes electrode positioning part and cutting part. The electrode positioning part is fixed relative to the frame and can reliably limit the electrode. The electrode is cut by the cutting part which moves relative to the frame.
[0025] Because the dust collection hood has a suction port near the electrode positioning part, and a dust collection channel is also provided on the side of the dust collection hood away from the suction port, the sealing shell of the dust removal structure is connected to the dust collection channel, and the suction pipe is connected to the sealing shell, forming a negative pressure space in the sealing shell. Moreover, a dust collection container is also provided in the sealing shell, and the dust collection container has a collection port that corresponds to the dust collection channel along the first direction. The dust collection container can accurately collect waste and debris from the dust collection channel.
[0026] During operation, the suction port effectively draws in waste and debris generated during the cutting process. This waste and debris then enters the negative pressure space through the dust collection channel, where they are subsequently drawn into the dust collection container by their own gravity and inertia. Compared to air blowing, negative pressure suction not only prevents debris from splashing outwards from the cutting position but also ensures that the debris inside the machine is stably stored in the dust collection container, guaranteeing reliable particulate matter control at the machine location and thus ensuring the quality of battery cell manufacturing.

[0036] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0037] like Figures 1 to 5 As shown, an embodiment of the present invention provides a tab cutting and dust extraction device, comprising: a frame 1, a cutting mechanism 2, a dust collection hood 3, and a dust removal structure 4. The frame 1 has a first direction Z. The cutting mechanism 2 is mounted on the frame 1 and includes a tab positioning part 21 and a cutting part 22. The tab positioning part 21 is fixedly disposed relative to the frame 1, and the cutting part 22 is movable relative to the frame 1. The dust collection hood 3 is disposed on the frame 1 and has a dust suction port 30 near the tab positioning part 21. A dust collection channel 31 is also provided on the side of the dust collection hood 3 away from the dust suction port 30.
[0038] The dust removal structure 4 includes a sealed housing 41 and an air intake pipe 42. The sealed housing 41 is mounted on the frame 1, and the air intake pipe 42 is connected to the sealed housing 41 to form a negative pressure space 40 in the sealed housing 41. The sealed housing 41 is connected to the dust collection channel 31, and a dust collection container 43 is also provided in the sealed housing 41. The dust collection container 43 has a collection port 44 that corresponds to the dust collection channel 31 along the first direction Z.
[0039] The electrode cutting and dust extraction device adopts a design of frame 1, cutting mechanism 2, dust collection hood 3, dust collection channel 31, and dust removal structure 4. The cutting mechanism includes electrode positioning part 21 and cutting part 22. The electrode positioning part 21 is fixed relative to the frame 1 and can reliably limit the electrode. The cutting part 22, which moves relative to the frame 1, performs cutting processing on the electrode.
[0040] Because the dust collection hood 3 is provided with a suction port 30 near the electrode positioning part 21, and a dust collection channel 31 is also provided on the side of the dust collection hood 3 away from the suction port 30, the sealing shell 41 of the dust removal structure 4 is connected to the dust collection channel 31, and the suction pipe 42 is connected to the sealing shell 41, forming a negative pressure space 40 in the sealing shell 41. Moreover, a dust collection container 43 is also provided in the sealing shell 41, and the dust collection container 43 has a collection port 44, which corresponds to the dust collection channel 31 along the first direction Z. The dust collection container 43 can accurately collect waste and debris from the dust collection channel 31.
[0041] During use, the suction port 30 effectively sucks up waste and debris generated during the cutting process. The waste and debris enter the negative pressure space 40 through the dust collection channel 31, and then, under the action of their own gravity and inertia, they fall fully into the dust collection container 43. Compared with the blowing method, negative pressure suction not only prevents debris from splashing outwards from the cutting position, but also allows the debris sucked into the machine body to be stably accumulated in the dust collection container 43, ensuring the reliability of particulate matter control at the machine position, thereby ensuring the quality of battery cell manufacturing.
[0042] In this embodiment, the dust collection hood 3 protrudes from the tab positioning part 21 along the first direction Z, and the suction port 30 is located on one side of the dust collection hood 3 corresponding to the tab positioning part 21. The first direction Z is the height direction. The design height of the dust collection hood 3 is greater than the height of the tab positioning part 21, and the suction port 30 is located on one side of the tab positioning part 21 corresponding to the dust collection hood 3. On the one hand, this ensures that the dust collection hood 3 can collect the waste and debris splashed out from the tab cutting position. On the other hand, the suction port 30 is located on the side of the tab positioning part 21, which avoids interfering with the normal operation of the cutting part 22 and can effectively suck up the debris splashed outward.
[0043] As a further preferred embodiment, the frame 1 includes a base plate 11 with through holes 12. The cutting mechanism 2 and the dust collection hood 3 are both located on one side of the base plate 11, with the dust collection hood 3 installed at the through hole 12. Dust removal structures 4 are spaced apart on the other side of the base plate 11, and a dust collection channel 31 is connected to the through hole 12 and connected to the sealing housing 41. Arranging the cutting mechanism 2 and the dust removal structure 4 on both sides of the base plate 11 makes more efficient use of space. The through hole 12 of the base plate 11 enables a conductive connection between the dust collection hood 3 and the dust collection channel 31, ensuring that the debris collected by the dust collection hood 3 can be fully introduced into the dust collection channel 31.
[0044] The sealed housing 41 includes sidewalls 410 arranged at relatively intervals, which are parallel to the first direction Z. An air intake port 45 is provided on the sidewalls 410, and an air intake pipe 42 is connected to the air intake port 45. It should be noted that any angle between the sidewalls 410 and the first direction Z, ranging from 0° to 10°, falls within the protection range defined by "parallel" in this embodiment. The air intake pipe 42 is connected to the air intake port 45 on the sidewalls 410, meaning that the air intake direction of the air intake port 45 does not coincide with or is parallel to the feeding direction of the collection port 44, preventing debris from potentially entering the air intake pipe 42 from the dust collection channel 31.
[0045] Furthermore, the dust collection channel 31 and the collection port 44 are arranged at intervals along the first direction Z, and the suction port 45 is correspondingly located at the interval between the dust collection channel 31 and the collection port 44. A filter cover 420 is also installed at the end of the suction pipe 42 corresponding to the suction port 45. The arrangement of the dust collection channel 31 and the collection port 44 at intervals along the first direction Z provides a certain space for the debris to fall, and the filter cover 420 further ensures the reliability of debris collection.
[0046] As a further preferred embodiment, the collection port 44 is a conical collection port. The conical collection port is widened along the first direction Z and close to the dust collection channel 31, which reduces the possibility of debris falling outside the collection port 44 and ensures the collection effect of small burr debris. In addition, a sealing door 46 is movably installed on the sealing housing 41, and the dust collection container 43 is detachably installed in the sealing housing 41, which facilitates the removal of the dust collection container 43 and the cleaning of internal debris.
[0047] In this embodiment, the cutting mechanism 2 includes a first mounting plate 23, a second mounting plate 24, a guide member 25, and a driver 26. The first mounting plate 23 is fixedly mounted on the frame 1, and the second mounting plate 24 is arranged at a distance from the first mounting plate 23 along a first direction Z. The guide member 25 is fixedly connected to the first mounting plate 23, and the second mounting plate 24 and the guide member 25 are guidedly engaged along the first direction Z. The driver 26 is driven between the first mounting plate 23 and the second mounting plate 24, and the cutting part 22 is assembled on the second mounting plate 24. By guiding the guide member 25 along the first direction Z, the movement accuracy of the second mounting plate 24 and the cutting part 22 is improved, ensuring the cutting accuracy of the cutting part 22 for the tabs.
[0048] Specifically, the second mounting plate 24 is also equipped with a linear bearing 27, and the guide member 25 is guided and engaged with the linear bearing 27. The driver 26 includes a cylinder 261 and a push rod 262. The cylinder 261 is fixedly connected to the second mounting plate 24, and a floating joint 263 is connected between the end of the push rod 262 and the first mounting plate 23. In addition, the frame 1 also includes a base 13 and a plurality of columns 14. The base 13 and the base plate 11 are arranged at intervals along the first direction Z. The plurality of columns 14 are fixedly connected between the base 13 and the base plate 11, and the sealing shell 41 is fixedly connected to the side of the base 13 facing the base plate 11. The base 13, the plurality of columns 14 and the base plate 11 constitute the overall structure of the frame 1. The sealing shell 41 is fixed to one side of the base 13 to ensure the rationality of the spatial layout.
[0049] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
